List Parts (GET uploadID)

Description

This multipart upload operation lists the parts of an archive that have been uploaded in a specific multipart upload identified by an upload ID. For information about multipart upload, see Uploading Large Archives in Parts (Multipart Upload).

You can make this request at any time during an in-progress multipart upload before you complete the multipart upload. Amazon Glacier returns the part list sorted by range you specified in each part upload. If you send a List Parts request after completing the multipart upload, Amazon Glacier returns an error.

The List Parts operation supports pagination. You should always check the Marker field in the response body for a marker at which to continue the list. if there are no more items the marker field is null. If the marker is not null, to fetch the next set of parts you sent another List Parts request with the marker request parameter set to the marker value Amazon Glacier returned in response to your previous List Parts request.

You can also limit the number of parts returned in the response by specifying the limit parameter in the request.

Requests

Syntax

To list the parts of an in-progress multipart upload, you send a GET request to the URI of the multipart upload ID resource. The multipart upload ID is returned when you initiate a multipart upload (Initiate Multipart Upload (POST multipart-uploads)). You may optionally specify marker and limit parameters.

Copy
GET /AccountId/vaults/VaultName/multipart-uploads/uploadID HTTP/1.1 Host: glacier.Region.amazonaws.com Date: Date Authorization: SignatureValue x-amz-glacier-version: 2012-06-01

Note

The AccountId value is the AWS account ID of the account that owns the vault. You can either specify an AWS account ID or optionally a single '-' (hyphen), in which case Amazon Glacier uses the AWS account ID associated with the credentials used to sign the request. If you use an account ID, do not include any hyphens ('-') in the ID.

Request Parameters

Name Description Required
limit

The maximum number of parts to be returned. The default limit is 1000. The number of parts returned might be fewer than the specified limit, but the number of returned parts never exceeds the limit.

Type: String

Constraints: Minimum integer value of 1. Maximum integer value of 1000.

No
marker

An opaque string used for pagination. marker specifies the part at which the listing of parts should begin. Get the marker value from the response of a previous List Parts response. You need only include the marker if you are continuing the pagination of results started in a previous List Parts request.

Type: String

Constraints: None

No

Examples

Example: List Parts of a Multipart Upload

The following example lists all the parts of an upload. The example sends an HTTP GET request to the URI of the specific multipart upload ID of an in-progress multipart upload and returns up to 1,000 parts.

Example Response

In the response, Amazon Glacier returns a list of uploaded parts associated with the specified multipart upload ID. In this example, there are only two parts. The returned Marker field is null indicating that there are no more parts of the multipart upload.

Example: List Parts of a Multipart Upload (Specify the Marker and the Limit Request Parameters)

The following example demonstrates how to use pagination to get a limited number of results. The example sends an HTTP GET request to the URI of the specific multipart upload ID of an in-progress multipart upload to return one part. A starting marker parameter specifies at which part to start the part list. You can get the marker value from the response of a previous request for a part list. Furthermore, in this example, the limit parameter is set to 1 and returns one part. Note that the Marker field is not null, indicating that there is at least one more part to obtain.
